- Our invention relates to bearings and more particularly, to floating bearings that-are utilized in combination with members'that have oscillatory movements relative to each other when inloperation; I g

The wobject of our invention, generally statedyis the provision ofa floating bearing that shall'be simple'and (efficient in operation and be readily' and economically manufactured and installed. 1'

A more specific object of our invention is to provide for rotating a floating bearing to cause the wearto be evenly distributed over the total bearing. surface. I 1

'A further object of our invention is to provide for rotating a floatingbearing that is utilized in combination with a stationary and an oscillatorymember for insuring that the wear shall be uniformlydistributed over the total bearing surface. L

IAno'therobject of our invention is to provide for rotating a floating bearing that is utilizedin combination with relatively movable members for insuring that the wear'shall be uniformly distributed over the total bearing surface, as the membersare being operated. a

Other objects of the invention will, in part be obvious and, in part, appear hereinafter.

This invention, accordingly, is disclosed in the embodiment'thereof shown in the accompanying drawing and comprises the features of construction, the combination of elements and the arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the objects of the invention, reference should be had-to the following detailed description, taken in connection with the accompanying drawing, in which 1 Figure 1 is a view, in elevation, of a floating bearing embodying the features of our inven- 'tion, parts'being broken away to show the arrangement of the elements of the structure.

Fig. 2 is a view, in vertical section, of a floating bearing, embodying the features of our invention, taken along the line IIII of 'Fig. 1.

7 Referring now to the drawing, 10 designates a floating bearing that maybe utilized in combination with a stationary trunnion 11 and'a rocker arm 12 disposed for-oscillatory movement relative tothe trunnionlll." The bearing 10 is provided with-a flange 15, the

outer surface of which is notchedhto form radial projections 16. It will be observed that the radial projections 16 extend only-i across the main portion of the outer face of the flange 15 in order to leave the outer portion 17 and the inner portion 18 of the face of the flange 15' to serve as bearing surfacesQ The outer face of the flange 15 is-notched in such manner that the projections are slightl below the planelof the bearing surfaces 1 and 18.

The floating bearing lO is held in placeby a cap 19 which makes. contact with the bear-' ing surface 18 on theouter face of the flange 15. The cap 19 has a threaded portion which 1 is screwed into a threaded opening of the sta tionary trunnion 11. Intermediate the cap 19 and the rocker arm 12 is an annulus 20 which makes contact with the bearing surface 17of rotated. Preferably, a screw 22 is provided to prevent any slipping that might occur between'the annulus 20 and the rocker arm' l2.

Itwill be observed that the'pawls 24 and 25 are provided to make engagement with the projections 16. The pawl 24 is-disposedin an opening provided therefor in the cap .19,=and the pawl 25 is disposed in an opening provid-' ed therefor in theannulus 20. The pawls 24 and 25 are resiliently pressed against th'elpro-l jections 16 by leaf springs27 and 28 respec-- tively. Likewise, the springs are adapted to prevent the pawls' from rotating within their openings, so that they will always bein their properpositions to make engagement with theprojections 16. The pawls 24 and 25,

which engage the projections, are straight on their engaging side and beveled onthe oppo-- site side, thus providinga wedge-shaped en'- gaging end. That is to, say, the'pawl 24, as viewed in Fig. 1, isfstraight on the lower side and beveled onthe upper side, whereas the pawl 25 is straight on the upper side and beveled on the lower side.

7 The radially disposed projections 16, with which the pawls engage (see Fig. 1), are

straight on one side and beveled on the opposite side to provide complementary notches or grooves for the Wedge-shaped engaging ends ofthe pawls. 10 III-operation when the oscillatory member '12, as viewed in Fig. 1, moves in a clockwise direction, the straight side of the pawl 25, which is carried by the annulus connected to the said oscillatory member, engages the 15 straight side of a projection 16 and, accordingly, rotatesthe bearing 1O in a clockwise direction. At the same time, the pawl 24, since the upperside thereof is beveled, merely rides over the projection 16,. with the result that it permits the floating bearing to. rotate "freely ina clockwise direction about the stationary member ll.

. Howeveiywhen the oscillatory member 12 moves in a counter-clockwise direction, the straight side of the pawl 24, which is carried by the". cap 19'connectedto the stationary vmember 11, engages the straight side of a projection 16 andsecures thefloating bearing 10 in a fixed position relative to the stationary meniber 11. Atthe same time,'the pawl 25,

since-the lower side thereof is beveled, merely.

rides over the said projections 16. According to the'foregoing, it is manifest that the cooperative action ofthe pawls 24 and 25 and the projections16 provides for intermittently rotating the floating bearing, notch by notch, as

the-member 12 oscillates Therefore-git is'to be noted that we have disclosed means for rotating-a floating bearingthat is utilized in combination with a stationary and an oscil-' latory member for insuring that the wear will be uniformly distributed over the total hearingsurface as the oscillatory member is'being operated:

We wouldst'ate, in conclusion, that while the illustrated example constitutesa practical" embodiment-of our invention, we do not limit ourselves strictly tothe exact details herein illustrated, since the structure :may be "considerably-varied without departing from the spirit of the-invention, as defined in the appended claims.

We claim as ourinvention: 1. In combination, a'floatingbearing hav" ing anoutwardly extending flange rotatively mounted upon the end of a stationary member, an oscillatory member rotatively' mount-- ed upon the said floating bearing, a member having an opening therein connected to the end of said stationary member, a member having an opening'therein connected'to said oscillatory member, radially disposed projections provided on the-flange of said bearing, a plurality .of-pawls for making engagements with I said projections, oneofsaid pawls being disposed in the opening of the member connected to said oscillatory member for rotating said bearin when t e said oscillatory member is being operated in one direction and the other pawl being disposed in the opening of the member connected to said stationary member for securing said bearing fixedrelative to said stationary member when the "said 0'scillatory member-is being operatediii-the opposite" dil rection,

2. In combination, a stationary member having an extended end, an oscillatory membercarried by the extended end of said stationary member, a floating bearing having an outwardly extending :flange interposed =Tbetween said stationary and oscillatory"mem-- relative to said stationary member bers, a portion of the outer surface-ofsaid' flange being provided withtradially disposed projections, a cap connectedto theendofsaid stationary member and, contactingfthe inner annular portion of said flange,; an annulus connected to thesa'id oscillatory-member and contacting the outer annular portion ofsaid flange, the said annulus surrounding the saidhem-I930.
